'Vampire Diaries' Season 6 Spoilers: Stefan Tells Enzo About Sarah Salvatore In Episode 11, EP Caroline Dries Teases Enzo's Move Against Stefan [VIDEO]

An extended promo video for "The Vampire Diaries" Season 6, episode 11 titled "Woke Up With a Monster" gave a preview about Enzo (Michael Malarkey) starting to destroy Stefan's (Paul Wesley) happiness. Executive producer Caroline Dries also teased what Enzo's move will be against the Salvatore vampire when the CW TV series returns from its holiday hiatus in January 2015.

In the promo video, Stefan is seen looking after his relative at an event but the mood changes when Enzo shows up. "What are you doing here?" Stefan asks the Augustine vampire.

Enzo tells Stefan that he disapproves of secrets between brothers. Then, Stefan finally reveals to Enzo his big secret which is the existence of Sarah Salvatore.

However, Enzo is still determined to dig deeper after Stefan revealed who Sarah is. "Why are you so intent on keeping it?" Enzo asks Stefan before the promo video ended. Watch "The Vampire Diaries" 6x11 Season 6 Episode 11 Extended Promo 'Woke Up with a Monster' (HD)" video below.

A Wet Paint report suggests Enzo's plan to destroy Stefan's happiness could involve Caroline Forbes (Candice Accola) after executive producer Caroline Dries teased what Enzo will do. "I can tease that [Enzo] needs to employ Matt to get what he wants. And he's going to come at Stefan from an unexpected angle," Dries shared.

Caroline Dries added that Enzo and Matt (Zach Roerig) will have an interesting relationship when the CW TV series returns from its holiday break. The executive producer further teased that the Enzo-Matt team up will reveal a "couple extra layers of Stefan" that the fans have not yet seen before.

With the tease on the "extra layers of Stefan," Enzo's plan against Stefan could either bring the Salvatore vampire closer to Caroline or further destroy their friendship. In the mid-season finale episode titled "Christmas Through Your Eyes," Stefan and Caroline shared a tender moment when Stefan comforted his best friend after telling the devastating news about her mom, Sheriff Forbes' (Marguerite MacIntyre), health condition.

The fans will find out what Enzo's unexpected angle is when "The Vampire Diaries" Season 6 returns on Jan. 22, 2015 with the Paul Wesley-directed episode titled "Woke Up With a Monster." The brand new episode will air at 8 p.m. ET on the CW Network.
